Captain Lacey Regency Mysteries Volume One contains the first three books and a couple of short stories in the Captain Lacey series by Ashley Gardner (pen name for Jennifer Ashley). It's on sale for $0.99/£0.99 at Kindle US/UK right now. The first half-ish of this series was traditionally published, and Gardner has continued the series by self-publishing, but I've liked all of the titles I've read - which is most of them. And, in any case, these (
The Hanover Square Affair,
A Regimental Murder,
The Glass House, and
The Gentleman’s Walking Stick) are among the ones that were traditionally published to start with.
